Been there, done that:
$ /usr/sbin/smartctl.exe -i /dev/hda
smartctl version 5.37 [i686-cygwin-xp-sp2] Copyright (C) 2002-6 Bruce Allen
Home page is http://smartmontools.sourceforge.net/
ATA/SATA driver is possibly a SCSI class driver not supporting SMART.
If this is a SCSI disk, try "scsi<adapter><id>".
Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)
A mandatory SMART command failed: exiting. To continue, add one or
more '-T permissive' options.
The drive is a Samsung 1614C which definitely supports SMART. Oh well,
so the answer is just "too bad", I assume...
